Magento2 How to get parent product(configurable) by child product using REST API

Magento2 does not have any APi.

So you have to create a new API point for this requirement.

Create below files:

 1. app/code/Devbera/Configurable/etc/webapi.xml 2. app/code/Devbera/Configurable/etc/di.xml 3. app/code/Devbera/Configurable/Api/ConfigurableManagementInterface.php 4. app/code/Devbera/Configurable/Api/ConfigurableManagementInterface.php 

Define api point at webapi.xml.

And code is below:

<?xml version="1.0" ?> <routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd"> <route method="GET" url="/V1/devbera-configurable/:childId"> <service class="Devbera\Configurable\Api\ConfigurableManagementInterface" method="getParentIdsByChild"/> <resources> <resource ref="anonymous"/> </resources> </route> </routes> 

And WebApi interface ConfigurableManagementInterface.php

And code is :

<?xml version="1.0" ?> <routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd"> <route method="GET" url="/V1/devbera-configurable/:childId"> <service class="Devbera\Configurable\Api\ConfigurableManagementInterface" method="getParentIdsByChild"/> <resources> <resource ref="anonymous"/> </resources> </route> </routes> 

ConfigurableManagement.php for getting parent product

And di.xml for rewrite interface with Model management class

<?xml version="1.0" ?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <preference for="Devbera\Configurable\Api\ConfigurableManagementInterface" type="Devbera\Configurable\Model\ConfigurableManagement"/> </config>
